Why offline speech recognition matters
If you’re still relying on cloud-based dictation apps, you’re trusting your conversations to servers you don’t control. Every time you speak into Apple Dictation, Otter, or Whisper Online, your audio travels to the cloud, sometimes stored, analyzed, or worse, breached.
In 2026, the privacy conversation has shifted. Users are asking uncomfortable questions: Where does my voice data really go? Who owns my transcripts? Can I use speech-to-text without the internet?
The answer is yes. And it’s better than you think.
Offline speech-to-text engines have matured significantly. They’re fast enough for real-time transcription, accurate enough for professional work, and they never leave your Mac. This guide compares the best options for your workflow.
Why local processing matters
Before diving into specific apps, let’s understand why offline matters.
Your audio never leaves your device. No cloud servers, no data breaches, no third-party access. You can transcribe on planes, in cars, in remote locations. Cloud-based systems have 1-3 second delays while local engines deliver results in milliseconds. Most local solutions are one-time purchases rather than $10-20/month subscriptions. And if you work in healthcare, law, or finance, local processing simplifies privacy rules for healthcare, legal, and financial work.
The tradeoff? You’ll need to download the speech recognition files (about 600MB to 2GB, similar to a large app). But that’s a small price for complete privacy and control. To understand the full picture, read why local speech recognition matters and our speech-to-text privacy guide for Mac.
Best offline speech-to-text apps for Mac
1. Dictato
Price: $9.99 (2-year license, renewable) macOS Requirement: Sonoma 14.0+ Best For: Universal app usage, real-time transcription, no-subscription users
Dictato takes a straightforward approach to pricing: $9.99 for a 2-year license with all updates included, unlimited usage, no subscription. The app keeps working even after the license period. You only renew when you want future updates.
Press a keyboard shortcut, speak into your Mac, release, and text appears at your cursor. Works in Slack, Gmail, VS Code, Word, Notion, or any app where you’d normally type. The key is universal text injection via system permissions, not copy-paste workarounds.
You get three engine options. Parakeet (recommended) supports 25 languages and delivers the fastest real-time performance at around 80ms response time. Whisper supports 99 languages with unbeatable coverage and a smaller download. Apple SpeechAnalyzer is built-in on macOS 26+ with 20 languages. You can swap engines based on your language or performance needs. Need Mandarin support but want a smaller download? Whisper. Transcribing English-only meetings and want speed? Parakeet.
On the feature side, there’s built-in AI proofreading via Apple Intelligence, a 30-language translation layer, two output modes (floating preview window or direct injection to cursor), and unlimited transcription history. Both push-to-talk and toggle recording modes are supported.
It does require system permissions (which any universal input app needs) and Microphone access. The macOS Sonoma minimum requirement might exclude older Mac users. And the large downloads aren’t ideal on slow connections, though the smaller Whisper engine works as a compromise.
In a market of subscription apps, Dictato’s 2-year license model is unusual. At roughly $5/year instead of $10-20/month, combined with real-time speed and universal app support, it’s the most practical offline option for Mac users who want things to work without fuss.

2. Whisper (local setup)
Price: Free (open-source) macOS Requirement: Any (requires programming knowledge) Best For: Developers and technically skilled users
Whisper is OpenAI’s open-source speech recognition model. You run it locally on your Mac. Free. No limits. No privacy concerns.
It supports 99 languages, more than any other option. The accuracy is impressive, especially for non-English languages and accents.
The catch: Whisper is free but requires programming knowledge to set up. It’s a developer tool, not something you download and use. There’s no built-in universal input. You’ll transcribe to a file and copy-paste, or build workarounds. Response time is 500-2000ms depending on your Mac’s power and the model size you download.
Whisper is powerful but not designed for everyday users. Most people will bounce off the setup process. For a side-by-side comparison of Whisper against polished alternatives, see Dictato vs Apple Dictation vs Whisper.
3. Apple Dictation (built-in)
Price: Free macOS Requirement: Any Best For: Casual users, those who value native integration
Apple’s built-in dictation is fast, familiar, and free. Works in most apps. Available since forever on the Mac.
Here’s where Apple gets clever. They call it “offline,” but the reality is mixed. Apple Dictation uploads audio to Apple’s servers for transcription, then returns text. It’s encrypted in transit, but it’s cloud-dependent. No internet means no transcription.
Accuracy is decent for common English, but Apple’s engine lags behind Whisper and Parakeet on technical terms, accents, and specialized vocabulary.
The new rewriting features in macOS 26+ are impressive (different tones and styles), but they require cloud processing too.
Apple Dictation is fine for quick notes, but it’s not a privacy solution. Marketing it as “offline” is technically misleading.
4. Superwhisper
Price: $4.99/month macOS Requirement: Intel/Apple Silicon Best For: Users willing to pay monthly for cloud-enhanced transcription
Superwhisper is a well-designed Mac app that uses OpenAI’s Whisper under the hood. It works universally, like Dictato.
Here’s the tension: Superwhisper is cheaper than Otter ($4.99 vs. $10-20), but it’s still subscription-based. You’re paying $60/year, or $120 over 2 years for something Dictato offers for $9.99 over the same period.
Superwhisper can route transcription through the cloud for potentially better accuracy, but you’re trading privacy for slightly higher accuracy in edge cases.
If you transcribe heavily and want a polished app with cloud backup of history, Superwhisper is solid. But the monthly fee adds up, and you have to trust their cloud infrastructure with your audio.
5. Google Cloud Speech-to-Text
Google also offers a speech-to-text service for developers building custom tools, but it’s not a consumer product. It’s cloud-only, paid after a free tier, and requires programming knowledge. Not practical for typical Mac users.
Comparison table
| App | Price | Works Offline | Languages | Speed | Works in Any App | Best For |
|---|---|---|---|---|---|---|
| Dictato | $9.99/2yr | Yes | 25-99 (your choice) | ~80ms | Yes | General users, all apps |
| Whisper (DIY) | Free | Yes | 99 | 500-2000ms | Requires setup | Developers |
| Apple Dictation | Free | No (cloud) | 20 | 1-2s | Most apps | Casual use |
| Superwhisper | $4.99/mo | Optional | 25-99 | ~200ms | Yes | Polished UI, monthly budget |
| Google Cloud | Free tier | No (cloud) | 120+ | 500-1500ms | No (developer tool) | Custom development |
Which should you choose?
If you want simplicity, an affordable 2-year license, universal app support, and real-time performance, go with Dictato. You’re done with monthly subscriptions.
If you’re technically skilled, want maximum language support, and don’t mind managing your own installation, Whisper is the right choice.
If you rarely transcribe and value native macOS integration above all else (but understand it’s cloud-based), Apple Dictation works fine.
If you transcribe frequently, prefer a polished app, and don’t mind a monthly subscription, consider Superwhisper.
Where local speech recognition is heading
Apple Intelligence, on-device AI, and growing privacy concerns are pushing Mac toward local-first processing. macOS 26 and your Mac’s built-in AI chip now have enough power to run sophisticated speech models in real-time.
Cloud-based dictation (Otter, Google, etc.) still exists, but these services are becoming the team-focused option for compliance-heavy use cases, not the default for individuals.
Expect 2026 to be the year offline speech recognition becomes the norm. The technology is ready. The privacy argument is won. Adoption is what’s lagging.
The privacy argument is stronger than ever
Recent breaches and corporate espionage cases have made one thing clear: cloud storage of anything sensitive, including voice recordings, is a liability. If your voice data exists on a company’s servers, it can be hacked, subpoenaed, or sold.
Local processing eliminates that entire attack surface. Your audio lives on your device. Period.
For freelancers, lawyers, therapists, doctors, and anyone handling sensitive information, local speech-to-text isn’t a nice-to-have. It’s a professional requirement.
Final verdict
If you transcribe regularly on macOS and care about privacy, switch to offline speech-to-text. The technology has matured enough to replace cloud-dependent apps entirely.
Dictato is the best option for most users: private, affordable, works everywhere, and requires zero technical setup. Whisper (if you’re technical) and Apple Dictation (if you’re casual) are legitimate alternatives.
Start by identifying which apps you dictate into most, then pick the tool that covers those apps without sending your audio to the cloud. That single decision eliminates most of the privacy risk. New to voice typing? Check out our beginner’s guide to dictation on Mac.
